Subscribing for signing process events Leave feedback
On this page
Signature class contains several events that are being called for different process stages
- SignStarted to handle process start event. This event is occur once Sign method is called
- SignProgress to handle progress event. This event occurs each time on signing each signature was completed.
- SignCompleted to handle completion event. This event occurs once Sign process was completed.
Here are the steps to subscribe for signing process with GroupDocs.Signature:
- Define required handler delegates to process signing events.
- Create new instance of Signature class and pass source document path or stream as a constructor parameter.
- Subscribe for required events
- Instantiate required SignOptions object
- Call Sign method of Signature class instance and pass signature options in it
GroupDocs.Signature expects ProcessStartEventHandler delegate to subscribe for SignStarted event
private static void OnSignStarted(Signature signature, ProcessStartEventArgs args)
{
Console.WriteLine("Sign process started at {0} with {1} total signatures to be put in document", args.Started, args.TotalSignatures);
}
private static void OnSignProgress(Signature signature, ProcessProgressEventArgs args)
{
Console.WriteLine("Sign progress. Processed {0} signatures. Time spent {1} mlsec", args.ProcessedSignatures, args.Ticks);
}
private static void OnSignCompleted(Signature signature, ProcessCompleteEventArgs args)
{
Console.WriteLine("Sign process completed at {0} with {1} total signatures. Process took {2} mlsec", args.Completed, args.TotalSignatures, args.Ticks);
}
private static void OnSignStarted(Signature signature, ProcessStartEventArgs args)
{
Console.WriteLine("Sign process started at {0} with {1} total signatures to be put in document", args.Started, args.TotalSignatures);
}
private static void OnSignProgress(Signature signature, ProcessProgressEventArgs args)
{
Console.WriteLine("Sign progress. Processed {0} signatures. Time spent {1} mlsec", args.ProcessedSignatures, args.Ticks);
}
private static void OnSignCompleted(Signature signature, ProcessCompleteEventArgs args)
{
Console.WriteLine("Sign process completed at {0} with {1} total signatures. Process took {2} mlsec", args.Completed, args.TotalSignatures, args.Ticks);
}
public static void Run()
{
using (Signature signature = new Signature("sample.pdf"))
{
signature.SignStarted += OnSignStarted;
signature.SignProgress += OnSignProgress;
signature.SignCompleted += OnSignCompleted;
TextSignOptions options = new TextSignOptions("John Smith")
{
// set signature position
Left = 100,
Top = 100
};
// sign document to file
signature.Sign("SignedSample", options);
}
}
